[Combined chemotherapy-radiotherapy study of small cell bronchial carcinoma: chemo-/radiotherapy vs radio-/chemotherapy]. / Kombinierte Chemotherapie-Radiotherapie-Studie des kleinzelligen Bronchuskarzinoms (CCR-Studie): Chemo-/Radiotherapie gegen Radio-/Chemotherapie.

The authors studied the effect of a chemo-/radiotherapy or radio-/chemotherapy on 52 cases of microcellular bronchial carcinoma, classification "limited disease". The survival curves were slightly better for the patients submitted to primary chemotherapy, but the difference was not statistically significant, and the curves coincided again after 18 months. 60 to 80% of the patients had no complaints or only unimportant complaints during more than half of their survival time. In 23 patients with "extensive disease" who received only a symptomatic therapy or a combined palliative chemotherapy, chemotherapy had a slightly better effect, but this was not statistically significant.
